1974, Open-File Report 74-7
The Geological Survey places in open files reports and maps that are preliminary or ephemeral in nature, are of interest to a small audience only, or consist of masses of essentially raw data. These reports and maps are available to the public and may be consulted at various Geological Survey...
Summary of tectonic and structural evidence for stress orientation at the Nevada Test Site
Wilfred James Carr
1974, Open-File Report 74-176
A tectonic synthesis of the NTS (Nevada Test Site) region, when combined with seismic data and a few stress and strain measurements, suggests a tentative model for stress orientation. This model proposes that the NTS is undergoing extension in a N. 50 ? W.-S. 50 ? E. direction coincident with...
Sedimentology of the Simmler and Vaqueros formations in the Caliente Range-Carrizo Plain area, California
J. Alan Bartow
1974, Open-File Report 74-338
The Simmler and Vaqueros Formations in the Caliente Range-Carrizo Plain area make up a large part of the thick Tertiary sedimentary sequence that was .deposited in a basin which lay along the southwest side of the present-day San Andreas fault. The evolution of this basin during Oligocene and early Miocene...

Geology and mineralogy of phosphate rock in the Bambui group near Cedro do Abaete and vicinity, Minas Gerais, Brazil
James Bachelder Cathcart
1974, Open-File Report 74-219
Discontinuous lenticular masses of phosphate rock are present near or at the contact between the green mudstone and the underlying red and yellow clay-stone units of the Serra da Saudade Member of the Rio Paraopeba Formation of the Bambui Group of late Precambrian to early Paleozoic age. The lenses are...

Water from the Coastal Plain aquifers in the Washington, D.C., metropolitan area
S.S. Papadopulos, R.R. Bennett, F. K. Mack, P.C. Trescott
1974, Circular 697
A brief study of the Atlantic Coastal Plain aquifers in the vicinity of the Washington, D.C., metropolitan area was made, using available data, to estimate the water-supply potential of these aquifers and to determine the possibility of developing an emergency water supply during droughts. Assuming that the data available are...
Water demands for expanding energy development
G. H. Davis, Leonard A. Wood
1974, Circular 703
Water is used in producing energy for mining and reclamation of mined lands, onsite processing, transportation, refining, and conversion of fuels to other forms of energy. In the East, South, Midwest, and along the seacoasts, most water problems are related to pollution rather than to water supply. West of about...
Floods in Indiana: technical manual for estimating their magnitude and frequency
L.G. Davis
1974, Circular 710
This manual provides methods for estimating the magnitude and frequency of floods on unregulated and unurbanized streams in Indiana that drain at least 15 square miles (38.8 square kilometres). The methods provide the design engineer with a means of estimating flood frequencies without having to analyze the records at individual...
Application of surface geophysics to ground-water investigations
Adel A. R. Zohdy, Gordon P. Eaton, Don R. Mabey
1974, Techniques of Water-Resources Investigations 02-D1
This manual reviews the standard methods of surface geophysics applicable to ground-water investigations. It covers electrical methods, seismic and gravity methods, and magnetic methods. The general physical principles underlying each method and its capabilities and limitations are described. Possibilities for non-uniqueness of interpretation of geophysical results are...

The worldwide search for petroleum offshore; a status report for the quarter century, 1947-72
Henry L. Berryhill
1974, Circular 694
At the end of 1972, offshore petroleum exploration was in progress on the submerged continental margins of 80 countries. Some 780 oil and gas fields had been discovered. Estimated worldwide volume of oil discovered offshore as of January 1, 1973, is 172.8 billion barrels of oil, or about 26 percent...
Movement and effects of spilled oil over the outer continental shelf; inadequacy of existent data for the Baltimore Canyon Trough area
Harley J. Knebel
1974, Circular 702
A deductive approach to the problem of determining the movement and effects of spilled oil over the Outer Continental Shelf requires that the potential paths of oil be determined first, in order that critical subareas may be defined for later studies. The paths of spilled oil, in turn, depend primarily...
Water quality of hydrologic bench marks; an indicator of water quality in the natural environment
James E. Biesecker, Donald K. Leifeste
1974, Circular 460-E
Water-quality data, collected at 57 hydrologic bench-mark stations in 37 States, allow the definition of water quality in the 'natural' environment and the comparison of 'natural' water quality with water quality of major streams draining similar water-resources regions. Results indicate that water quality in the 'natural' environment is generally very...
